Perfect height to eliminate using a riser block. I am using these on an M4 with a 4x32 scope. But these will allow up to a 40mm without much trouble. After my 1st session the cross bolts loosend up. I put a drop of blue locktite on each one. Mo problems. Seem pretty stout ass well.
Pros: Can mount a 40mm scope w/o a riser - saves weight
Cons: Need to use blue locktite on the cross bolts.
